Karin Giannone (born in 1974 in Johannesburg, South Africa) is a South African-born British television newsreader working in the United Kingdom. She returned from maternity leave on 6 February 2010 and is the London-based main presenter of the weekend daytime coverage on BBC World News.

Giannone's family moved from Johannesburg to the United Kingdom when she was aged two. She was raised in Edinburgh, Sussex and Kent. She studied modern languages at Cambridge University, where she graduated with a first class honours degree; she speaks French, German and Italian.

She was the editor of Cambridge University’s "Varsity" student newspaper in 1994-5, which led to work experience at Anglia Television. She joined the regional ITV station on graduation in Norwich as a news trainee in 1997, producing, reporting and presenting for regional news bulletins. In 1999 her language and broadcasting skills helped her land a role as a reporter and presenter for Channel 4’s Football Italia series, where she covered the Italian Soccer scene for a season, flying between the UK and Italy every week. She returned to Anglia in 2000 as a presenter and reporter, this time for the programme for the east of the region covering Norfolk, Suffolk and Essex. She also followed troops from the region for a series of reports from Afghanistan in 2002.
